Here is a prayer from Gerhard Tersteegen (1697 – 1769):

O Prince of Life, teach us to stand more boldly on your side, to face the world and all our adversaries more courageously, and not to let ourselves be dismayed by any storm of temptation;
may our eyes be steadfastly fixed on you in fearless faith;
may we trust you with perfect confidence that you will keep us, save us, and bring us through by the power of your grace and the riches of your mercy.
Amen.
